This document gives an overview of the different device operation modes and the RF transmissions 
performance of the key. In this document the device is referenced as "key", even if the mechanical 
backup key might be separated from it.

For an overview of the electrical function blocks, please see the document "Block Diagram of
Nissan DPF I – key 2

nd

Bundle".

The key has three main operating modes which differ regarding of the signal transmitting with the
RF:

•

· Immo

Immobilizer transponder mode

•

· RKE

Remote key functionality

•

· PASE

Passive key functionality

When the key is operating as an immobilizer transponder, the communication is done via a "contact 
less interface" depending on a magnetic coupling. The transponder is the passive side of the link and 
there is no RF transmission from it involved in any aspect.

This mode refers to use the key as a remote control unit to initiate actions on the vehicle such as 
open or close door latches. RF transmission depends on a user activating (a button pressing) on the 
key. During the button pressing the amount of telegrams are sent on the RF channel.
